Software Defined Radio (SDR) info

Software-defined radio (SDR) is a radio communication system where components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system. While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which used to be only theoretically possible.Here are a few SDR radio information links. I will add more as I find them or other people recommend them:Wikipedia link to SDR : http://en.wikipedia.org/wiki/Software-defined_radioSDR Radio roundup listing of Radios: http://www.rtl-sdr.com/roundup-software-defined-radios/Listen to some SDR radios around the world: http://websdr.org/A blog about RTL-SDR (RTL2832U) and cheap software defined radio: http://www.rtl-sdr.com/Ham Radio Science - some good SDR info: http://www.hamradioscience.com/SDR Transceiver.com is a brief overview of several SDR transceivers on the market:http://www.sdrtransceiver.com/

about this blog:

Managing repeater and NET frequencies was a tough problem for me. So I started to keep my notes on frequencies, NET's and Club and Hamfest information here. Over time we have added all kinds of information of interest to Upstate NY Radio enthusiasts. I will also try to update old posts with confirmations and updates as I get new information .I have a broad range of interests and love to share much of the cool stuff I stumble across.

We will try to post information for Upstate New York from Albany west to Buffalo and from Binghamton north through the 1000 Islands and Adirondacks. You may notice more news from Central and Northern NY (because that's where I live and recreate.....), but we will try to cover as much of the Upstate New York Region as possible.
